Nyob rau hauv kev tiv thaiv ntawm inert roj, 2-methylphenylsulfonylhydrazide (1.1 mmol), benzonitrile (1.0 mmol), palladium catalyst (2 mol%) thiab biquinoline (bq, 3 mol%) tau dispersed nyob rau hauv cov organic hnyav (2 mL) ), ces. H2O (2 mmol) tau ntxiv, thiab qhov kub tau nce mus rau 80 ° C rau 6 teev.Tom qab ntawd cov tshuaj tiv thaiv tau muab rho tawm peb zaug nrog Et2O (5 mL), cov theem ntawm cov organic sib xyaw ua ke, thiab cov kuab tshuaj tau tig-qhuav hauv qhov txo qis.Cov khoom siv raw khoom tau raug rau kab chromatography ntawm silica gel kem (300-400 mesh), thiab cov eluents yog roj av ether, kom tau cov khoom lag luam 2-methylbenzophenone.Cov khoom siv tshuaj tsis muaj xim lossis lub teeb daj pob tshab kua.Lub melting point yog hais txog 134 ° C.Siv ua tshuaj nruab nrab.
